Patented June 26, 1945 comma John 11. Hampton, Oaklyn, N. J., assignorto Beaumont Birch Company, Philadelphia, Pa., a corporation ofPennsylvania Application February 11, 1944, Serial No. 521,906

3 Claims.

The principal object of the present invention is to simplify and improvethe construction and operation of conveyers, more particularly inrespect to the chains thereof.

Other objects of the invention will appear from the followingdescription at the end of which the invention will be claimed.

In the following description reference will be made to the accompanyingdrawing forming part hereof and in which,

Figure l'is a transverse vertical section of a conveyer embodyingfeatures of the invention; and

Figure 2 is a cross sectional view taken on the line 2-2 of Figure 1.

Referring to the drawing, the conveyer chain includes links I disposedin pairs and pivot pins 2 connecting the ends of the pairs of links androllers 3 on the pivot pins between the links I. 5 are right angle bendelements .secured at one of their ends to the pivot pins and they areshown as having shoes 6 at their, other ends. The right angle elementsare shown as of tubular form and mounted on the pivot pins anddetachably secured thereto by pins I. The described assemblagesconstitute flight portions. 1 are tie bars secured to the flightportions and disposed in range of the links of the chain and theyoperate to limit the pivotal motion of the flight portions in onedirection. In some cases it is desirable to connect the tie barsadjustably with the nights so that their range of movement may beincreased or diminished. 8 are vertically disposed working and returnconduits and they include a return bend. One of the a jacent walls 8 ofeach of the conduits merge into a single partition wall It at the returnbend. II is a discharge opening provided in the outer wall of theworking conduit near the return bend. i2 is a sprocket wheel pivotallymounted at the return bend. The teeth of this wheel are notched at theirends it for engagement with the rollers 3 and the roots of these teethare notched as at It for the accommodation of the tie bars 1*. Thepartition wall It is forked or bifurcated for the accommodation of thesprocket wheel and at its end it contacts with the axle or journal ofthe sprocket wheel.

From the foregoing description it will be observed that the pivot pins 2perform the double function of connecting the links and flight portions.Furthermore, in the event of breakage of the flight portions they can bereadily repaired.

It may be remarked that the rollers 3 greatly diminish frictionalresistance and, therefore, eflect a reduction in the power required foroperating the conveyer.

I claim:

1. In a conveyor, the combination of a conveyer chain having linksdisposed in pairs and pivot pins connecting the ends of the links androllers on the pivot pins between the links, right angle bend elementsconstituting flight portions secured at one of their ends to the pivotpins and having shoes at their other ends, tie bars secured to saidflight portions and disposed in range of the links of the chain andoperative to limit the pivotal motion of the flight portions, verticallydisposed working and return conduits including a return bend and spacedadjacent inner walls which merge into a single partition wall at thereturn bend, a discharge opening provided in the outer wall of theworking conduit near the return bend, a sprocket wheel located at theend of the partition wall and having teeth for engagement with therollers on the pivot pins, said sprocket wheel being recessed for theaccommodation of the tie bars, and said partition wall being forkedtoaccommodate the sprocket wheel.

2. In a conveyer, the combination of a conveyer chain having linksdisposed in pairs and pivot pins connecting the ends of the links, androllers on the pivot pins between the links, right angle bend elementssecured at one of their ends to the pivot pins and constituting flightportions, and tie bars secured to said flight portions and disposed inrange of the links of the chain and operative to limit the pivotalmotion of the flight portions.

3. In a conveyer, chain having links disposed in pairs and pivot pinsconnecting the ends of the links and rollers on the pivot pins betweenthe links, right angle bend elements secured at one of their ends to thepivot pins and constituting flight portions, tie bars secured to saidflight portions and disposed in range of the links of the chain andoperative to limit the pivotal motion of the flight portions, a sprocketwheel constructed for engagement with the rollers and notched to: theaccommodation of the tie bars.

some a. n'mr'ron.

the combination of a conveyor.
